introduction
HTML, HyperText Markup Language, is the cornerstone of building modern networks. Whether you are a fledgling developer or an experienced web architect, understanding the role of HTML in web content structure is crucial. Through this article, you will gain insight into how HTML defines the skeleton of a web page, how to organize content through tags and attributes, and how to leverage HTML best practices to improve web page accessibility and SEO performance.
Review of basic knowledge
HTML is a markup language used to describe the structure and content of a web page. It does this through a series of tags and attributes. Each HTML document starts with the tag, containing two main parts: and . The section usually contains metadata, such as titles, character encodings, and references linked to CSS files, while the section contains user-visible content.
The core of HTML is its semantic tags, which means that each tag has a specific meaning and purpose. For example, <h1></h1> to <h6></h6> are used for titles, <p></p> are used for paragraphs, <ul></ul> and <ol></ol> are used for lists, and so on. By using these tags correctly, we can not only make the web page more visually structured, but also allow search engines and assistive technologies to better understand and process content.
Core concept or function analysis
Definition and function of HTML
The full name of HTML is HyperText Markup Language, which is used to define the structure and content of a web page through a series of tags and attributes. The core function of HTML is to provide a standardized way to display information so that web pages can be displayed correctly on different devices and browsers.
For example, the <h1></h1> tag is used to define the main title on the page, while <p></p> tag is used to define the paragraph. Through these tags, we can clearly organize the content to make it easy to read and understand.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>My First Web Page</title>
</head>
<body>
<h1 id="Welcome-to-My-Website">Welcome to My Website</h1>
<p>This is a paragraph of text.</p>
</body>
</html>How HTML works
When the browser loads an HTML file, it parses the tags and properties in the file, and then builds a Document Object Model (DOM) based on this information. DOM is a tree structure that represents the hierarchy and content of a web page. The browser converts the DOM into a visual web page through the rendering engine.
The working principle of HTML also includes functions such as handling hyperlinks, form submissions, embedding multimedia content, etc. These functions are implemented through specific tags and attributes, such as <a></a> for links, <form></form> for forms, <img alt="The Role of HTML: Structuring Web Content" > for pictures, and so on.
Example of usage
Basic usage
The basic usage of HTML includes using common tags to organize content. For example, to create a simple web page, you can use <h1></h1> to <h6></h6> tags to define the title, <p></p> tags to define the paragraph, and <ul></ul> and <ol></ol> tags to define the list.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>My Simple Page</title>
</head>
<body>
<h1 id="Main-Title">Main Title</h1>
<h2 id="Subheading">Subheading</h2>
<p>This is a paragraph of text.</p>
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>
</body>
</html>Advanced Usage
Advanced usage of HTML includes the use of semantic tags to enhance web page accessibility and SEO performance. For example, tags such as <header></header> , <nav></nav> , <main></main> , <article></article> , <section></section> , <aside></aside> and <footer></footer> can help search engines and assistive technologies better understand web structure.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Semantic HTML Example</title>
</head>
<body>
<header>
<h1 id="My-Website">My Website</h1>
<nav>
<ul>
<li><a href="#home">Home</a></li>
<li><a href="#about">About</a></li>
</ul>
</nav>
</header>
<main>
<article>
<h2 id="Article-Title">Article Title</h2>
<p>This is the main content of the article.</p>
</article>
<aside>
<h3 id="Related-Links">Related Links</h3>
<ul>
<li><a href="#link1">Link 1</a></li>
<li><a href="#link2">Link 2</a></li>
</ul>
</aside>
</main>
<footer>
<p>© 2023 My Website</p>
</footer>
</body>

When using HTML, common errors include unclosed tags, unquoted attribute values, incorrect tags, etc. These errors may cause the web page to display abnormally or fail to pass verification.
Methods to debug HTML errors include using browser developer tools to check and fix errors, using HTML validators to check the validity of code, and developing good coding habits, such as using the code editor's automatic completion and formatting capabilities.
